Abstract
PURPOSE Exercise-induced laryngeal obstruction (EILO) is suspected when dyspnea associated with upper airway symptoms is triggered by exercise. This condition affects mainly adolescent athletes. Visualization of the obstruction, while the patient is experiencing the symptoms during continuous laryngoscopy during exercise (CLE-test) is the gold standard for diagnosing EILO. Our study aims to evaluate the prevalence of EILO in a population presenting exercise-induced inspiratory symptoms (EIIS) or uncontrolled asthma with exertional symptoms. The second objective was to evaluate the diagnostic strength of laryngology consultation (LC) and pulmonary function tests (PFTs). METHODS All patients referred to our center for EIIS or uncontrolled asthma with exertional symptoms were included. EILO diagnosis was made if Maat score was > 2 for patients with CLE-test or if there were inspiratory anomalies on PFTs and LC. The sensitivity and specificity of LC and PFTs as diagnostic tools were calculated considering CLE-test as the gold standard. RESULTS Sixty two patients were referred to our center for EIIS or uncontrolled asthma with exertional symptoms. EILO was diagnosed in 28 patients (56%) with associated asthma in 9 patients (18%). The sensibility and specificity of LC for supraglottic anomalies were 75% and 60%, respectively. The sensibility and specificity of PFTs were 61% and 89%, respectively. CONCLUSIONS There was a high prevalence of EILO among patients with EIIS and uncontrolled asthma. Some clinical characteristics might guide the diagnosis. Nevertheless, CLE-test remained the gold standard for EILO diagnosis and identification of the dysfunctional upper airway site to provide specific management.

Abstract
PURPOSE Exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (EILO) are two disorders commonly considered when athletes complain of exertional dyspnea. They are highly different but often confused. We aimed to address this diagnostic challenge and its consequences in elite athletes. METHODS We included all athletes competing at national or international level, referred to our institution for workup for EILO during 2013-2016. We diagnosed EILO from video-recorded laryngoscopy performed during maximal cardiopulmonary treadmill exercise (CLE-test). Symptoms and previous diagnostic evaluations were obtained from referral letters and chart reviews. RESULTS EILO was diagnosed in 73/101 referred athletes, of whom 70/73 had moderate/severe supraglottic obstruction and 3/73 had primarily glottic obstruction with only minor supraglottic involvement. Of the 73 athletes with EILO, we were able to identify objective tests for asthma in 55 participants, of whom 22 had findings supporting asthma. However, 58/73 had used asthma therapy at some time previously, with current use in 28. Only three reported that asthma medication had improved their exercise related breathing problems, two of whom with tests confirming asthma. Treatment for EILO improved breathing problems in all but four. CONCLUSIONS Objective testing verified EILO in most of the referred athletes. EILO coexisting with asthma was common, and large proportions had used asthma medication; however, few reported effect on exercise related breathing problems. Unexplained persistent exertional dyspnoea must not lead to indiscriminate escalation of asthma treatment, but instead incite investigation for EILO, either as a co-morbidity or as a differential diagnosis.

Abstract
The diagnosis of exercise-induced laryngeal obstruction (EILO) should be suspected when exercise triggers inspiratory stridor. EILO is common in adolescent populations and has a significant impact on sports. Identification of laryngeal obstruction during continuous laryngoscopy during exercise (CLE) is the gold standard diagnostic tool for this disorder, which is not widely known in France. The challenge faced by otolaryngologists is to identify, among patients referred by pulmonologists or sports physicians, those with exercise-induced inspiratory symptoms or poorly controlled exercise-induced asthma, in whom a diagnosis of EILO is strongly suspected. Laryngoscopy at rest may reveal a laryngeal, glottic or supraglottic abnormality predictive of obstruction at increased inspiratory airflow. When pulmonary function tests are normal or in the case of failure of treatment of exercise-induced asthma, the otolaryngologist must complete the examination by a CLE test to confirm the diagnosis of EILO and identify the site of obstruction. This examination is well tolerated, minimally invasive and allows identification of the site of airflow obstruction, allowing specific conservative or surgical treatment. This technical note describes in detail clinical examination and CLE testing in patients with suspected EILO.

Abstract
Exertional dyspnea is common in health and disease. Despite having known for centuries that breathlessness can arise from the larynx, exercise-induced laryngeal obstruction is a more prevalent condition than previously assumed. This article provides a brief overview of the history, epidemiology, and pathophysiology of exercise-induced laryngeal obstruction.

Abstract
Exercise-induced laryngeal obstruction (EILO) is the term for the condition previously named vocal cord dysfunction and paradoxical vocal fold motion. It is defined by glottic or supraglottic obstruction during periods of intense exercise. Not all patients respond to conventional therapy with speech-language pathology, behavioral health interventions, and treatment of contributing conditions. In this edition of Journal of Voice, the authors describe a novel series of respiratory retraining techniques, now called Olin EILOBI (EILO biphasic inspiratory) breathing techniques, specifically designed for athletes with EILO. This case presentation describes the discovery of one of these techniques during a session of therapeutic laryngoscopy during exercise. The patient was an adolescent with EILO who demonstrated a positive response to therapy with a variant of these techniques over a few days, having previously struggled with symptoms despite multiple sessions of conventional respiratory retraining over the course of months.

Abstract
INTRODUCTION Exercise-induced laryngeal obstruction (EILO), the condition previously known as paradoxical vocal fold motion and vocal cord dysfunction, is characterized by inappropriate glottic or supraglottic obstruction during high-intensity exercise, causing exertional dyspnea, frequently with stridor. EILO is definitively diagnosed through upper-airway visualization during a characteristic episode. Although respiratory retraining is a primary therapy for EILO, many patients report symptom persistence despite adequate performance of traditional techniques. This report describes three novel breathing techniques for EILO, the Olin EILOBI (EILO biphasic inspiratory) breathing techniques. We include a teaching process and case series with patient-reported assessments. MATERIALS AND METHODS Following descriptions of the techniques and teaching process, we present data from a questionnaire offered to all patients who learned at least one of the techniques between September 2015 and March 2017. Subjects evaluated (1) expectation setting, (2) teaching processes, (3) their ability to implement the techniques during high-intensity exercise, and (4) perceived clinical effectiveness. RESULTS Ninety-five percent of eligible patients participated, a primarily young, female, and Caucasian sample. Over 50% of subjects competed at the high school varsity level. Sixty-two percent of subjects perceived reasonable expectations, and 82% positively evaluated the teaching process. Seventy-nine percent were able to employ their technique in the high-intensity activity of choice, and 66% perceived clinical effectiveness with the techniques. CONCLUSIONS The Olin EILOBI breathing techniques are novel respiratory retraining techniques for use in high-intensity exercise. Case series subjects reported reasonable expectations, a helpful teaching process, the ability to use these techniques during high-intensity exercise, and perceived clinical effectiveness.

Abstract
Exercise as an important part of life for the health and wellness of children and adults. Inducible laryngeal obstruction (ILO) is a consensus term used to describe a group of disorders previously called vocal cord dysfunction, paradoxical vocal fold motion, and numerous other terms. Exercise-ILO can impair one's ability to exercise, can be confused with asthma, leading to unnecessary prescription of asthma controller and rescue medication, and results in increased healthcare resource utilization including (rarely) emergency care. It is characterized by episodic shortness of breath and noisy breathing that generally occurs at high work rates. The present diagnostic gold standard for all types of ILO is laryngoscopic visualization of inappropriate glottic or supraglottic movement resulting in airway narrowing during a spontaneous event or provocation challenge. A number of different behavioral techniques, including speech therapy, biofeedback, and cognitive-behavioral psychotherapy, may be appropriate to treat individual patients. A consensus nomenclature, which will allow for better characterization of patients, coupled with new diagnostic techniques, may further define the epidemiology and etiology of ILO as well as enable objective evaluation of therapeutic modalities.
